a
There were 3 cases of bacterial pneumonia caused by Stenotrophomonas maltophilia, Serratia, rubidiae, and Bukholderia gladioli exclusively identified by culture (the relevant targets are not included in the PCR panel). In 6 patients with pneumonia, C. albicans was identified in cultures of tracheal aspirate and considered as co-pathogen by the primary physician (target not included in the PCR panel).
